Baylor University would like to construct a confidence interval for thedifference in salaries for business professors (group 1) and criminal justice professors (group 2). The university randomly selects a sample of 52 business professors and finds their average salary to be $85,232. The university also selects a random sample of 69 criminal justice professors and finds their average salary is $65,775. The population standard deviations are known and equal to $9000 for business professors, respectively $7500 for criminal justice professors. The university wants to estimate the difference in salaries between the two groups by constructing a 95%confidence interval.

Compute the upper confidence limit. Round your answer to 2 decimals, if needed.

Please show work, thanks
